N. coronata is a subspecies of mitrata and there is no evidence that 
mitrata and papillosa are sub specifically connected, even though trans- 
vaalensis has the papillae less developed than in the more western 
birds. The following measurements will best illustrate the difference in 
the size of the casque of all these forms, the three from Windhuck, 
S. W. . African Protectorate, representing the type series of N.p.

GUTTERA EDOUARDI SYMONSI subsp. nov. 
Differs from the typical G. edouardi (Hartl.) from the coast of Natal 
in having only the faintest traces of chestnut coloration in the feathers 
of the lower neck, back, scapulars, chest and flanks and the white spots 
more distinctly blue, the whole general effect produced by these differ- 
ences being very marked. G. lividicollis Ghigi (Mem. Acc. Sc.Instit., 
Bologna, vi, pi. ii, 1905) does not appear to differ from the typical G. 
edouardi in the feather coloration, but has been founded upon the colora- 
tion of the skin of the neck. No notes were made upon the colour of 
the soft parts of this new subspecies at the time of their capture, and 
I am therefore unable for the present to detail them ; but Mr. R. E. 
Symons, who was kind enough to send a series of five specimens' to the 
Transvaal Museum, but is away from home at the time of writing, has 
promised to remedy the omission when next he is able to secure speci- 
mens ; the lack of these particulars does not, however, affect the status 
of the new subspecies. The specimens examined are two pairs of adults 
and an immature male, the last still retaining black and buffish down on 
the back of the head and short black feathers, some tipped with dirty 
white, on the throat ; the crest is also not fully developed. Essentially 
the immature specimen does not differ from the adults — but traces of 
bars instead of spots of bluish white are to be seen in the outer wing- 
coverts, abdominal region and flanks, and particularly on the tail 
feathers. The type series (of which T.M. No. 11585 is the type) was 
taken at Karkloof (3,500ft.), Natal, by Mr. R. E. Symons, after whom 1 
have pleasure in naming the subspecies. 
Dimensions: Adults, length of wing from tip of primaries 260 275 
mm ; tail 140-160 ; metatarsus 80 ; culmen 22-25. Immature, wing 950, 
tail 130, metatarsus 72, culmen 22.
